What is repulsing protons and electrons?

They behave as if they are the same charge.

They attract, which is why an electron is BOUND to
an atom and why it takes energy to free it.

Maybe it's not attraction.

Perhaps unlike charges repel each other just half as much
as much as like charges repel each other.

You have to solve the Schroedinger equation in the 1/r potential to see
the answer. It's because the electron's de Broglie wavelength is much
much greater than the proton's de Broglie wavelength, so the two don't
'touch.' It's one of those things where the probabilistic nature of QM
makes our classical intuition unreliable, and applying the logic of
'billiard ball' particles gives the wrong answer. If you can't solve
differential equations, you can't understand.
